Description
Technical field
The utility model belongs to the seal arrangement technical field, particularly relates to a kind of pipe liquid filled form seal structure.
Background technique
The automobile lightweight has become controlling the trend of current auto manufacturing development, the continuous development of the urgent day by day and lightweight technology that requires along with energy-saving and emission-reduction in recent years, and hollow structural component has appearred in automobile manufacturing field.Traditional hollow structural component adopts the welding of forging and pressing part more and makes, because the stress concentration phenomenon of this part is comparatively obvious, and exists a large amount of weld seams and residual processing amount, these all can increase the weight of car load greatly.If adopt liquid-filling shaping technology shaping hollow structural component, can not only reduce weld seam and residual processing amount, alleviate complete vehicle weight, reduce the quantity of manufacturing procedure, reduce production costs, and can also improve the precision and the mechanical property of hollow structural component effectively.
Pipe liquid filled forming technique is to utilize the liquid medium that will have certain pressure of cutting somebody's hair to charge in the tube chamber as punch, under the axial force acting in conjunction that fluid pressure and pipe end applied, pipe will deform and be fitted on the mold cavity, thereby obtain the part of required geometrical shape.This technology has that forming limit is big, precision is high, and the formation of parts quality is good, the advantages such as part of can be shaped special material, labyrinth.
Because pressure required during pipe liquid filled the shaping is higher, so the sealability at pipe two ends seems particularly important in the forming process.The sealability of wherein cutting somebody's hair is directly connected to the part forming quality, if seal failure in the production process, not only part can't be shaped, and very easily leads to major accident.At present, cutting somebody's hair that domestic liquid-filling shaping uses adopts rubber seal to seal mostly, because the impaired back of rubber seal is difficult for changing, therefore greatly influenced manufacturing efficiency; Though some adopts the manufacturing efficiency of cutting somebody's hair of rigid construction sealing higher, be difficult to when impaired it is carried out maintenance, and this sealing means is bigger to the damage of pipe inwall; Though some adopts cutting somebody's hair of seal ring structure can not cause damage to the pipe inwall, shortcoming is its complex manufacturing, and cost of production is higher.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of simple in structure, good sealing effect, manufacturing efficiency height, and the high pipe liquid filled form seal structure of back part inner surface quality that is shaped.
In order to achieve the above object, the pipe liquid filled form seal structure that the utility model provides is installed between cutting somebody's hair of pipe liquid filled shaping and the pipe, and it comprises fixed block, movable part, guide spiro rod and rubber seal; Wherein the internal axis position of guide spiro rod connects and is formed with a through hole, is formed with screw thread on the surface, during the rear end insertion is fixed on and cuts somebody's hair; Fixed block is sleeved on the front end surface of guide spiro rod in the form of a ring; The internal axis position of movable part connects and is formed with a tapped through hole, and it is sleeved on the middle part outer surface of guide spiro rod in the mode that is threaded; Rubber seal is then on the guide spiro rod surface between fixed block and the movable part.
The anterior face of described movable part caves inward and is formed with ladder, and radially outwards outstanding formation of posterior face and outer circumferential face are positive hexagonal structure, facilitates the use spanner and operates.
Be formed with screw thread on the internal surface of described fixed block, it is threaded in after the front end surface of guide spiro rod with welding or adhering method and guide spiro rod and is fastenedly connected.
The front end external diameter of described movable part is identical with the external diameter of fixed block and rubber seal, and is simultaneously identical with the outer end internal diameter of pipe.
The external diameter of described movable part intermediate portion is identical with the external diameter of pipe.
The pipe liquid filled form seal structure that the utility model provides is to adopt rigid element associatings such as rubber seal and fixed block and movable part as the seal arrangement of cutting somebody's hair, not only processing technology is simple for it, with short production cycle, cost is low, can satisfy the technological requirement of axial feeding feed supplement in the forming process, and long service life, be easy to maintaining, good sealing effect, can adapt to the requirement of 200MPa with interior hydraulic seal automatically, the while can be changed impaired rubber seal at short notice, thereby has reduced the manufacture cycle of pipe liquid filled shaping widely, and the inner surface quality height of the back part that is shaped, and the requirement of the modern enterprise automatic production that is content with very little.
